This isn't exactly new news, but for anyone who didn't know: Sol (aka
Marty;-) now has a genuine group of sunspots on its earth-facing
hemisphere. Just about any telescope equipped with a safe solar
filter ought to show the group. I made an observation and sketch
earlier today using a 60mm f/11 achromat refractor at 70x.
Sketcher,
To sketch is to see.

Scientists were quoted only yesterday on the news as saying that the
lack of spots could result in a mini ice age.
Sketcher may just have saved the planet from a fate worse than ... OMG
global warming is back on the agenda!  |

The cover of the latest Sky and Telescope seemed to imply that the Sun
had shut down. A lack of sunspots, of course, doesn't really mean
that. Now, if all of a sudden, the solar neutrino flux had gone down
to zero, *that* would be time to start worrying.
Fortunately, I don't really think we have to worry about the Sun
ceasing to shine. Other stars similar to the Sun have not been noted
to engage in that sort of behavior. And there is no anthropogenic
pollution that reaches that far either.
Ah, an idea for a science-fiction story - where the neutrinos emitted
by fission power plants cause stars to shut down! God's ecology
regulations!

Your take on the cover. Not everybody's. Did you bother to read the
article?

I did read the article, and it was clearly about only the sunspots,
although an 0.1% decrease in sunlight was noted. But the cover could
be taken as implying that, which I thought could confuse people.

RF radiation does. We're polluting the cosmos with our inane
television and radio broadcasts. Just what we need, Howard Stern and
Rush Wharrgarbl as interstellar diplomats.

A pleasure to make your acquaintance, Dr. Soran.

Certainly, that's one of the last strong radio sources that points
outwards. Still, the signals aren't strong compared with natural
sources.
